v cleaning preparations on an aqueous basis so-called dry ll-IAIR COSMETIC PREPARATION BACKGROUND OF INVENTION 1. Field to which invention relates.

The present invention relates to preparations for the 5 cleaning of human hair and removing fatty substances from it.

2. The prior art In addition to the use of liquid hair washing and shampoos have been known for a long time. These products are more particularly used when the use of water is not possible or does not appear to be desirable.

These dry shampoos usually consist of an absorbing powder base, for example rice starch, talcum, kieselguhr. On application they are either rubbed into the hair or, in accordance with a proposal as made by the Austrian patent specification 217,640, they are applied to the hair in the form of an aerosol spray composition. After acting on the hair they are brushed out to remove them from the hair.

In the case of the use of these dry shampoos it is found that there is the disadvantage that some of the material remains on the hair and the scalp, something which leads to increased scurf formation and possibly also irritation of the scalp. Furthermore, the action of the fat removing powder on the hair is not sufficient. In the case of the use of so-called powder sprays there is also, owing to the high solids content, frequently a stoppage of the aerosol nozzle valve. I

SUMMARY OF INVENTION It has now been found that a sufficient removal of fatty'material from the hair and cleaning of the hair can be carried out while avoiding the above-described disadvantages if the dry cleaning of the hair is carried out with a material which contains a wateninsoluble organic polymer in an organic solution, preferably with the addition of a cationic tenside or surface active material. It is found that after such treatment the hair is sleek and lustrous and can be satisfactorily combed and brushed.

Particularly advantageous is the use of this preparation in the form of an aerosol spray composition. The hair cleaning and defatting composition is used in this case in such a manner that the material is applied at a distance of 20 to 40 cm from the hair and after being allowed to act for a short time is vigorously combed out of the hair. In this case the hair styling remains completely and no residues remain on the hair.

Water-insoluble organic polymers which can be used in products in accordance with the invention include polymethacrylates, more especially polybutylmethacrylate. However, it is also possible to use other 55 water insoluble organic, preferably synthetic,

polymers. As part of the invention it is also possible to use, naturally, copolymers, more particularly copolymers made up of alkylmethacrylates and other monomers and possibly also polymer mixtures in as far as they have suitable properties. The proportion of the organic polymer is 0.5 to percent by weight of the total composition, and preferably 4.0 percent by weight.

Solvents in the materials in accordance with the invention for cleaning and defatting human hair include for example dichloromonofluoromethane and trichlorotrifluoromethane, whose overall composition lies between approximately 25 and approximately percent of the overall composition, preferably 50 percent of it.

The preparation in accordance with the invention contains preferably also surface active substances present in a quantity between approximately 0.01 to approximately 3.0 percent by weight of the total com position. Materials preferably used include cationic tensides or surface active materials, for example quaternary ammonium compounds. It is, however, also possible to make the use of suitable non-ionic or ampholytic tensides, for example alkylene oxide condensates with alkylphenols, fatty alcohols and fatty amines, amine oxides, such as lauryldimethylamine oxide, betaines and long-chain alkylamino-carboxylic acids alone or in compatible mixtures with each other or with cationic surface active materials.

The use of the materials in accordance with the invention for the cleaning and defatting of human hair is generally carried out in the form of an aerosol spray composition. In this respect the addition of a propellant gas or mixture of such gases is necessary. Suitable propellant gases include for example dichlorodifluoromethane, monochlorotrifluoromethane, monochIorodifluoromethane, monochlorodilluorochtanc, dichlorotetrafluorocthanc, dilluoroelhanc, oc-

tafluorocyclobutane, propane, butane, monofluorodichloroethane, trichlorotrifluoroethanc, trichlorofluoromethane, and

dichloromonofluoromethane. It is naturally also possi ble to use suitable mixtures of propellant gases. The high boiling point fluoromethane and fluoroethane derivatives mentioned in the present context by way of example only can naturally be used exclusively in mixtures with low boiling point propellant gases and operate simultaneously as solvents. The pure propellant gas proportion lies preferably between 25 and approximately 75 percent by weight.

Preparations in accordance with the invention can naturally also include additions conventional in hair cosmetic preparations such as for example aromatic substances and refatting additions such as silicone oils or higher fatty acid esters, preferably isopropyl myristate.

The superior effect of the material in accordance with the invention over preparations previously used as dry hair washing materials is demonstrated by the following comparative test.

The fatty hair of 10 test persons was divided with a parting along the middle of the head and one side was sprayed with an aerosol shampoo of conventional composition (preparation A) while the other side was sprayed with the hair defatting and cleaning material (preparation B) in accordance with the invention at a distance of approximately 30 cm. After allowing the materials to act for approximately 1 minute each half of the hair was thoroughly brushed out. On both sides a defatting action was detected after brushing out. However, the defatting action was stronger on the side treated with the preparation B in accordance with the invention. The main difference between the two sides however lay in that the hair on the side treated with the preparation B was sleeker and more lustrous after brushing out, while the side treated with the conventional preparation A had a gray deposit which could be seen to lie on the hair and the scalp. This difference was found to be the more pronounced the higher the fat content of the hair before treatment. The two preparations had the following compositions:

The conventional aerosol dry shampoo was obtained by charging percent by weight of a mixture of 60 SiO and 40 percent starch, with 85 percent by weight of a propellant mixture of 50 percent trichloromonofluoromethane and 50 percent trichlorodifluoromethane in an aerosol container.

The preparation in accordance with the invention was made as follows:

4.0 by weight polybutylmethacrylate 0.4 by weight cetyltrimethyl ammonium bromide 0.8 by weight silicone oil 0.2 by weight perfume oil 49.6 by weight trichloromonofluoromethane 45.0 by weight dichlorodifluoromethane A material in accordance with the invention can comprise substantially 0.5 to 10 percent by weight polybutylmethacrylate, approximately 25 to percent by weight organic solvent, approximately 0.01 to approximately 5.0 percent by weight cationic surface active material and approximately 25 to 75 percent by weight of an aerosol propellant.

I claim 1. An aerosol composition for cleaning and degrea'sing human hair, housed within an aerosol container, consisting essentially of about 0.5 to 10.0 percent by weight of a water-insoluble polymethacrylate dissolved.

in about 25 75% by weight, based on the total preparation, of an organic solvent therefor, and further containing about 25 75 percent by weight of aerosol propellant and less than 3.0 percent by weight of cationic surface-active substance.

2. A composition according to claim 1, wherein said polymethacrylate is polybutyl methacrylate. 

2. A composition according to claim 1, wherein said polymethacrylate is polybutyl methacrylate.
